BACKGROUND Primary tracheal tumours are rare, so few physicians have extensive experience of their management. No direct comparisons have been made of surgical and radiotherapy treatment. METHODS A postal survey of cases presenting in the last 10 years in the United Kingdom was conducted.

Primary Tracheal Schwannoma

Primary neurogenic tumors of trachea are extremely uncommon and account for only about 9% of all neoplasms of trachea. Tracheal schwannoma is among the rarest of them and there is no unanimity of opinion regarding its treatment. We report a 30 year-old woman with symptoms of airway obstruction due to primary tracheal schwannoma. She was suffering from cough and exertional dyspnea. She was admit...

Primary Brain Tumours

Introduction Primary CNS neoplasms represent 2% of all cancers and are the sixth most common group of tumours in adults and the second most common form of cancer in children, accounting for 20% of cancers in children under the age of 15 years. Although the incidence of tumours metastatic to the central nervous system outnumbers the combined incidence of tumours arising in the brain, spinal cord...

Primary intrathoracic neural tumours.

TERMINOLOGY Each axon cylinder is encased in a sheath of Schwann cells, and the tumour arising from this, the specific nerve sheath, is the Schwannoma or neurilemmoma. Groups of axon cylinders comprising a peripheral nerve are enmeshed in a non-specific sheath of fibrous tissue, and tumours arising from this non-specific nerve sheath are neurofibromata. In some nerve sheath tumours clear histol...
